IMPROVEMENT IN CULTIVATORS'.

Specification forming part of Letters Patent No. 57,619, dated August28, 1866.

To all whom it may concern:

Be it known that I, JACOB BERGEN, of Plain Township, in the county ofStark and State of Ohio, have invented new and useful. Improvements inCultivators; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, of which Figure 1 is a perspective view. Fig. 2 is afront view. Fig. 3 is a cross-section, and Fig.

' the machine easy of transportation from place to place, or lowered toany required point, so as to give the teeth or colters any degree ofpenetration into the soil; and also in the application of a back braceto the tooth or colter standard, extending from the back of the teeth orcolter to the frame, and thus making the colter standard much strongerto resist any bending that might be caused from the colter striking anyobstacle.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A is the frame, of wood or other material;

B,'the seat for the driver, arranged in the manner before specified; G,the wheels; D, the standards of the teeth or colters; E, the backbraces, so arranged, in connection with the frame A and standard D, asto afford. a firm brace to the colters E. F is the main part of theaxle; G, the crank portion thereof, and H the axle for the wheels.

To the main axle F, I attach a lever. I, which has on one of its sides asliding rod, K, which is pushed downward by the spring M, and has thehandle N at its upper extremity. The lower extremity of the sliding rodK works into notches in the bent iron L, which is fastened to the frameat either extremity.

It will be seen that, by the moving of the lever I from one end of thearc L to the other through the action of the bent axle H G F G H, thepoints of the colter E will be raised from the ground or lowered, so asto penetrate to any required depth into the soil, the sliding rod K, inconnection with the bent iron L, serving to maintain the machine in anyrequired position.

What 1 claim as my invention, and desire to secure by Letters Patent,is-' 1. The peculiar arrangement of the bent axle H G F G H, inconnection with the frame A and the wheels Gr, substantially in themanner and for the purpose specified.

2. The peculiar arrangement of the back braces E and frame A, in themanner and for the purpose specified.

JACOB BERGEN.
